Given info:-

Evaluate the expression 8-5xy^3 for x=3 and y = -2.

8 - 5xy^3

⇛8 - 5(3)(-2)^3

⇛8 - 15(-2*-2*-2)

⇛8 - 15(-8)

⇛8 - (-120)

⇛8 + 120

Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

$81^{x+1}+3^{4x}=246$

$81=3^4$

Rewrite equation: $3^{4\left(x+1\right)}+3^{4x}=246$

$3^{4\left(x+1\right)}=3^{4x}\times 3^4$

$3^{4x}\times 3^4+3^{4x}=246$

Factor out $3^{4x}$ :

$3^{4x}\left(3^4+1\right)=246$

Divide both sides by $(3^4+1)$ :

$\frac{3^{4x}\left(3^4+1\right)}{3^4+1}=\frac{246}{3^4+1}$

$3^{4x}=\frac{246}{3^4+1}$

$3^{4x}=\frac{246}{82}$

$3^{4x}=3$

Anything to the power of 1 is itself. Hence,

$4x=1\\$

$x=\frac{1}{4}$

sattari [20]

Answer:

Step-by-step explanation:

Convert them all to the form y = mx + c

4x + 3y = 15

3y = -4x + 15

y = -4/3 x + 5

3x - 4y = -8

-4y = -3x - 8

4y = 3x + 8

y = 3/4x + 2

y + 1 = 4/3(x - 6)

y + 1 = 4/3x - 8

y = 4/3x - 9

y = 3/4x - 5
